C because the the smallest thing then the other ones because it never said what kind of size of it
Answer:
63.750KeV
Explanation:
We are given that
Initial velocity of second electron,
Radius,

1 m=100 cm
Magnetic field,B=0.0370 T
We have to determine the energy of the incident electron.
Mass of electron,
Charge on an electron,
Velocity,
Using the formula
Speed of electron,
Speed of second electron,

Kinetic energy of incident electron=
Kinetic energy of incident electron=
Kinetic energy of incident electron=
1KeV=1000eV
Dissolves limestone and other rocks.
Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
Answer:
